IMPROVEMENT IN HARROWS.

Specification forming part of Letters Patent N0. 170,637, dated November30, 1875; applica-tion filed September 11,1875.

To all whom it may concern:

Be it known that I, HENRY MEILI, of Yellow Stone, in the county of LaFayette and State of Wisconsin, have invented a new and Improved Harrow,of which the following is a specification:

In the accompanying drawing, Figure l represents a top View, and Fig. 2a front elevation, of my improved harrow.

Similar letters of reference indicate corresponding parts.

The present invention relates to certain imv provements in foldingharrows; and it consists in the combination of front guard and lock-barswith the central bars and pivoted toothed bars, as will be hereinaftermore fully described.

In the drawing, A represents the central parallel main pieces or bars,which are suitably hinged together to connect the symmetricallyconstructed barrow-sections. The central bars A are provided at their frontends with upwardly-curved metallic draft-pieces B, of suitable height,that are connected at their ends by a lateral chain, a. The draft-piecesB serve for the purpose of transmitting the draft equally to each bar,so that when either barrow-section is raised, for avoiding obstructionsor other causes, the other section works with the saine facility withoutbeing' lifted oi' the ground, and endangers thereby the animals or thedriver. The draft, being applied to the draft-pieces B, tends to keepthe teeth inthe ground without lifting the central bars, and

produces the uneven and unreliable working of the barrow. The toothedbars O are pivoted to plates b of the central bars, and swing inparallel direction to each other symmetrically at both sides of thecentral axis of the barrow, the teeth being so applied that each runsseparately and equidistantly from the other, so as to rake the groundthoroughly at whatever angle bars G may be set toward the center. Theparallel position of the toothi d bars G is secured by longitudinalpieces D, which are pivoted, to the upper and lower side of bars C, andcurved in such a manner that the bars may be closely folded up withoutbeing hindered by the teeth coming iu contact with connecting -pieces D.The rear bars C have handles d, by which either harrow-section may bereadily lifted from the ground, as required, to avoid stumps or otherobstructions. The central bars are also provided with teeth that till upthe intermediate distance between the teeth of the swinging bars O. Thefront ends of the central bars A are connected to the swinging frontbars C by rlhe lock-bars E, being arranged at the front of the barrow,serve also as guard-pieces to carry the harroW-sections overobstructions, exposing thereby the teeth in a less degree to violentshocks and injury.

The toothed bars may be swung out to considerable width, and after usebe folded toward the central bars, taking up a small space for beingreadily placed 011 a wagon for transportation to and from the fields.

Having thus described my invention, I claim as new and desire to secureby Letters latent- The combination of the lock and guard bars E E withthe central beams A A, toothed pivoted bars O, and connectingbars D D,said bars E E being pivoted to the beams AA near their front or draftends, and connected with the bars C, as and for the purpose set forth.
